I’m not entirely sure why I find this model compelling. The proportions are pleasing and it reminds me of Philip Shen, the way it suddenly locks together at the end. I would call it simple, but it is manifestly not. The lines are simple. The pre-folding is persnickety — fussy, if you will — and pulling the legs down one at a time deforms the model in a distracting way. For all of that, I like this model. Maybe you will, too. Here are some diagrams.
It’s called Brazier after a similar traditional model — the Japanese is hibachi, I believe — a raised box on four legs. Francis Ow has made a lovely model that looks something like this (diagrammed in his self-published Geometrical Origami), but the similarity is not structural.
For extra credit, you can reckon the volume. It’s easier than you might suspect.
